This equipment requires an external overcurrent protection device. To comply with
safety regulations, a 5.0 A time-lag fuse, or a previously approved 1-amp thermo-
magnetic circuit breaker (ABB-S281-UC-K-1 or equivalent), must be installed in
the power line. Be sure to observe the correct polarity of the DC connection as the
wrong polarity may destroy the external line fuse
The Teldat 5Ge-Rail has one earth terminal (on the rear panel). It must be groun-
ded through a cable with a section measuring, at least, 2 mm
This equipment must be grounded. Never deactivate the ground conductor or op-
erate the equipment in the absence of a properly installed ground conductor. Con-
tact the appropriate electrical inspection authority or an electrician if you don't
know whether suitable grounding is available. When installing or replacing the unit,
the ground connection must always be established first and disconnected last.
